[MENTION=5294687]festor[/MENTION] & G2K0 : could be. As the engine revs, the car's voltage will rise to typical 13,2V or a tad higher. When off, it should read 12,6 or lower. Maybe there's some kind of odd grounding problem that wrecks havoc on the ouku's detection line. I would first double check the grounding of the system (MEASURE IT ! IT SHOULD BE NEAR ZERO). If that's okay, It would be good to do a test with a sepperate 12V (grounded to the car of course) and use that 12V only for simulating the 12V Camera Reverse Detection line, just to see if it makes any difference. But it is indeed an odd problem.

@ G2K0 : I can't find the exact type of mic anymore, but it looks like a deadringer of this one : http://www.benl.ebay.be/itm/ES006US...t=US_Computer_Microphones&hash=item51a8901927

As said, it looks ugly, but mine looks like that, with the little black "noise cap" on it. I've mounted it at the side of my front curtosy light, facing to the drivers' side and ran the cable from the headunit through the A-Post underneath the plastic cover, and exiting the curtosylight whole in the roof liner. I know most people will hook their mics on the A-Post at the driver side, but in my experience, the central mount works better, especially if you've got a noisy car like mine was in its original state.

@ G2K0 : that waze thing made me think. On older notebooks, high-traffic BT communication could very well interfere with the Wifi system. Even till today, some modern laptops have issue with that due to poor design or less-than-optimal placed antenna's inside the laptop. Long shot, but you could try experimenting with that if all else fails. Or maybe the powerdrain on the system is too much for it to keep the whole thing stable. I guess you're using an unpowered hub ?

@ BrownRT : I do see your point and respect your point of view and spitting up the thread is a logical thing to do, but on the other hand, the amount of discussion on this thread is 98% Ouku, quite a lot of "is this a real 4.0" and a lot less about the I802 of which there are 15-or-so post at the max. I'm trying to make it clear at each comment that if I'm talking I802, it's clearly stated in the comment. As the I802 hasn't reached near the same kind of level of support there's no valid reason to have a sepperate I802 topic, but as I'm convinced I802 users can pick up a lot of good ideas coming from you Ouku users, I'd be so bold and ask to allow us to stick around for the time being. We won't misbehave. Much. :)

Since I can't post links, I'll give instructions: Google "Roadnav S150 ANDROID" and click the link from the "smartauto24.com" site.

Is this the same manual that you have? It may save you some scanning time!

I'll be getting in contact with HifiMax directly as it seems to be cheaper through them than anywhere else I've seen online. Nice to know they have good customer service as well. A 2 year warranty isn't bad either!

[MENTION=5294687]festor[/MENTION] I got YouTube working with a 3pd app from Google Play. I got earlier suggestion that maybe Flash player was the issue for "unsupported fileformat" but havent had time to test it.

That wasn't a jab at you friend. The topics of these 100 plus pages include development, general questions and different devices.
[Android Head-Units] kaween:
Nah, I know. I just wanted to express the notion that I'm not here to diss or disrespect you guys/girls either. I'm just glad I found this thread : I've been riding it since the first pages, and I've learned loads from this topic ! :highfive:

---------- Post added at 09:42 PM ---------- Previous post was at 09:29 PM ----------

Yep, Right on ! That's the one !

The unit comes with another small leaflet (quick launch) which explains the various connectors and cables, but that's the main manual alright.

And yes, the people at HifiMax really gave me a good feeling about the deal.

Just send a mail to Winnie (sales05@hifimax.net) and she won't let you down.

You can tell her Kris "that difficult customer from Belgium" send you. She'll remember allright. Poor thing. :)
[Android Head-Units] kaween:
Cool (I802 related)

Glad I could help a bit !

Anyhow, the next thing I'll be trying is the Wifi Torque connection. As long as we don't have a commonly available solution for the OTG situation or a rom with secundary BT support, enabling Ad-Hoc and running a Wifi ELM327 when needed will be the best solution for me. I already had a BT/USB Module, but I simply bought a Wifi one too. With prices like this these days (16€ for a ELM327 with Wifi ?) there's no point in waiting till a better (USB or BT) solution comes along. If it comes, great. If not, at least we'll have a workable solution at a fraction of the price of say a Ca-Fi 602100 or comparable.

Personally, I thing It would be great to have a better Radio App though. The standard one isn't bad, but I don't really like it either. Instead of the enormous FM Dial, I would have simply put Frequency + Station Name, with enough space to have a decent RDS info area. And direct acces to presets instead of first having to press the "menu" thingy. I wonder if something like Effem or Spirit FM would work on this unit.

Having a Santa Fe that new, that's Canbus for sure. Does the Interface get Power ? Is it SELECTED ? Because on the S150, Canbus Type has to be selected in the manufacturers menu. If that's not set right, nothing will work. On my S150, you get into manufaturer mode by going to BT, and dial "#*98723" + call. There you can set/define stuf lke RDS, but also Canbus and Canbus type. Maybe something went wrong there ?
[Android Head-Units] brownrt:
Finally!

Hey Guys,

Finally got my unit installed and thought I'd post some pics. This device is slightly different from the OP however the root method by Hal9k has provided does work. In a previous post I mentioned that it wasn't working on my unit. I didn't realize that the file was updating 4 files so it took about 5 minutes and installing a new image....hence the 20 second boot times people are getting.

I installed it in my 2004 Mercedes C230k Hatchback.

As you see my unit does not have rotary knobs and has green illumination with tactile buttons. When I get some time, I will look into soldering on some orangish leds.

I got the dash kit from crutchfield, and it sits rather nicely in the dash. The only problem is that the inner bezel is a little thick partially blocks access to the rarely accessed SD card...so no biggie. I want to make sure I can print a new bezel at HacDC before I start shave and polishing.

Comes with iPod integration [located in glovebox] The gps antenna is completely in my glove box as well with no reception issues using Waze and my Freedompop hotspot (I definitely recommend you guys checking out freedompop)

Also, because there is no light sensor, i will look into apps that dim the backlight on time profiles like tasker.

Here are some pics

It works!! How did you find the factory settings code ? I suspected that there is one but did not know how to enter on it. I enter and I see a LONG list of CAN bus types, every name in Chinese. It was set to first one. So let's try second one. Go to steering wheel settings, select one button and It works! Even more, it automatically set the other buttons did not have to set anything else. All commands work, both radio related and phone related. You solved my problem, thanks a lot :). Also I played with the remote, opened the box put it back (was not properly closed first time) and it works. I need to be close to unit no more than 10 cm and more close to the right upper corner, but it takes the commands. I don't see when I will use the remote anyway.

I also set the radio to Americas, it was set to Europe, not sure it makes a difference, I thought the frequencies are the same at least on FM. RDS was set to on and it works (get the names of stations - small ). I don't think we have other functionality here like in Europe.

I'm pretty happy now, you made my day.

I have a question about Torque, did not try the BT reader, but reading this thread I understand that does not work ? (BT) ? It's Gingerbread related or specific to this device ? I was using the app with my Nexus in JB without problems. Don't really intend to have it live, so for checking I can use my tablet or phone anyway, so more just a curiosity question.

About the radio, I think we have to live with it. It's not perfect but not to bad (check some other Chinese units Radio app, looks worst). Radio is not part of Android API this is why there are very few app, as every manufacturer uses it's own radio access. I doubt you will find another one which works, it's not like a player it require access to hardware without a standard interface.
[Android Head-Units] adit9989:
I'm not an expert but I watch a few YouTube vide, which recommend to set the magnetic GPS antenna on a metallic part somewhere in dash near unit. The dash plastic will not degrade the signal but the metal itself will increase the sensitivity it's like all your car is part of the antenna.(at least is what they say).
[Android Head-Units] brownrt:
I think you misread my post. I do not have a reception issue. I have perfect reception even with the antenna in the glove box. Usually 9/12 satellites by the time I fire up the Gps test app. Although the WPA supplicant app doesn't seem to work well for me.
[Android Head-Units] adit9989:
Thanks again. You are right. I see that this automotive units have a slower refresh cycle than tablets and phone, which is understandable. The good thing is that they stay longer on market so better chance that you get people with different expertise working on them. From what I've seen the "S150" model (sold under different names ) is one of the newest ones. The hardware is not bad for automotive units, I don't see dual and quad core units to soon. One of the main reasons is that most units are running Windows CE, Android ones are harder to find. CE does not support multicores so the manufacturer has no choice. Also CE maximum resolution 800x480 which keep the resolution at this level even if for Android it would be easy to pop it up.

Splitting the thread would be nice but you would need a moderator with access to move posts, there is already a lot of valuable info here. I'm glad that I found this thread, I see that other tried to start threads about other units but they are completely empty, whoever needs them can not find them.
[Android Head-Units] kaween:
The one pointed by G2K0 didn't work on the S150 either. After copying it, the S150 lost all capability to connect to anything. Wifi devices were still visable (altough it took far longer), but connection was impossible. Stuck on "obtaining IP" or "out of range", and scanning took ages. After looking around, this kind of problem is quite common, as the wpa_supplicant must be compliant to the android version. Triend all kinds of combinations, but to no avail : nada. :(

Found another, older version which SEEMS to act correctly. As the OUku runs 2.3.7, and the S150 runs 2.3.4. , this behaviour could turn out to be logical.

Wifi stays stable with that version, wifi scanning works perfectly too. Now I'll have to await the arrival of the wifi elm327. Gah, hope this will work. If it does, I'll post it on the forum for others to benifit.

Developers???

It has been a while since we heard anything from developers.

Is anyone working on updating to a newer version of android, or in fixing or adding features to the current rooted version?

I would love to hear some feedback from developers.

As always, thank you for all of your time and efforts.
[Android Head-Units] brownrt:
Thanks for the compliment. I've been installing car audio for 15 years and I'll be dammed if I'm goons let some some do it just because it's a Mercedes, lol.

Would you mind sharing the link for this older WPA supplicant you found?

If really like to be able to use my phone as a fall back for when the cruddy Sprint network fails on my otherwise awesome freedompop hot spot

Also I think I found the issue with torque acting weird with Waze. I believe the issue actually has to do with insufficient power from the USB hubs. I have found that if I initialize torque first, the issue doesn't occur. I could be wrong and the issue had something to do with quick Bluetooth.

Speaking of which, do any of you know of a way to get the Bluetooth to turn on automatically on boot?
[Android Head-Units] kaween:
Hi there.

I've included the supplicant version instead. Unrar it, fire up ES explorer, backup your original wpa_supplicant and copy this one. Be sure your wifi is disabled before you do that, Reboot the device, enable wifi ... and with a bit of luck, it works for you. Mind you, I still haven't been able to test it myself fully, but at least I still have a working Wifi after installing this version. My original file is about 127 K big, the G2K0 one was 285K, this one is 235K. So SOMETHING must be different. :) Would love to hear your feedback.

As for the Waze + BT thing : that's why I asked if the used USB hub was a non-powered one. :) It "feels" logical as possible problem.

And on a side note : I know the feeling (installing the radio). I don't like to be at the "mercy of others" when it comes to my own stuff. Or like the DIY mantra goes over here : "Dingen die je zelf doet, doe je meestal beter". (The stuff you do yourself often get done better). My car originally didn't even have a 2din slot, had to convert the dashboard to do that. First time I went to the dealership, the mechanic said "he didnt" know Dacia made 2din Versions now" :D

[MENTION=4809719]MANDROIDS[/MENTION] : well, let's all hope it's "the silence before the storm". But in the mean time, we better take "care of each other as good as we can".;)
[Android Head-Units] kaween:
PS : Victory !!!:victory:

I just tested that older supplicant file with a W7 notebook in ad-hoc. The S150 recognizes the Notebook as a Ad-Hoc device and lists it with the (*) notation. So a Wifi ELM327 will probably work too. Fingers crossed !

How to root Chinese 2 din android 4.0 car head unit

Hi Briarwood,

I am new to this forum and trying to find information to root my Chinese 2-din car head unit. I see that you were able to root your head unit with Hal's ROM. I believe my head unit is a WinCE 6.0 + Android 4.0 unit. I wonder if this unit is rootable. I am willing to experiment rooting it and share my experiences with you and other members. Can you point me to the right direction where I would be able to download the ROMs and instructions. Thank you.

[Android Head-Units] brownrt:
This thread is for pure android units only. That being said, While your unit may be root able, you will be rooting WinCe as android is being run as an app so to speak

At least that's what I believe to be true. Try searching elsewhere on the forum but again this thread is for pure Android units only.
[Android Head-Units] kaween:
Hi APnet.

Welcome ! But I'm just a newby myself too, hardly know what I'm doing most of the times. :)

I fear BrownRT is right. Those WinCE+Android run a sort of "emulated android". There's no "getting through" when the Android is basically running as a WinCE task. :( The complete hardwarelayer is done by the underlying WinCE, so you just can't "punch through" to the "nice stuff" like you can on "Pure Android".

I'm not saying it can't be done, I'm just saying people much, much smarter than me tell me it can't be done. Sorry for the bad news, I hope you still have a great headunit and may it serve you long and well !

Woot!

Das nächste Bier geht auf mich

Have you been able to use wifi tethering from your phone with the wpa supplicant? I've had spotty luck with. Fortunately I have the Bluetooth odb device..
[Android Head-Units] kaween:
Nah Denn, Die Welt Ist Wirklich Sehr Klein. Ein Prosit Auf Die Gemüdlichkeit. :)

Bisst Du Dass Oder Ist Das Google Translate ? :)

Haven't focused on wifi tethering. I know the machine is stable when connecting to my Phone's Wifi when the Phone is in AndroidAP mode. I had a stable connection with my Fujitsu Siemens W7 machine, but the supplicant did do some spotty stuff with the OBD Wifi as you can see, so yeah, I wouldn't be surprised "results may vary". I've found a couple of other supplicants in the mean time which all reacted somewhat different, I'll post the other that gave me usable results tomorrow. Maybe it makes some difference in your case too. But now, I'm off to bed. Long day ahead, and I did the Wifi thingy todya while I was working on my central heating at home. Ready now, beat, exhausted, but too giddy to find sleep.

The BT OBD is no doubt the best solution, altough I'd rather have a working OTG and a direct USB OBD running myself. But beggers can't be choosers, and I'm glad my Wifi works stable. Everything that comes now is extra.

Ah, and an extra thanks to you too ! If it wasn't for your "that supplicant didn't work for me" remark, I wouldn't have started looking for solutions in that direction either.

What I would need now is a way to have a "one button go static" switch that lets me change the Wifi settings of the S150 at the touch of a button to static and back to dynamic. I know stuff like that exist, strangly enough Tasker won't let me do something like that (not even sure Tasker would run on the S150), but "Wifi Static" from Farproc seems promising.

Pumpkin Unit pure android phonebook problem

I have a problem with the phonebook in my unit. I link my phone and I link the phonebook to the unit and everything works perfectly. I select a contact, I will pulse the button to call the contact and it works.

The problem is that when I disconnect the phone from the unit again after I connect the phone to the unit and phone agenda appears again, but do not make the call when I select the contact.

I have to move the phonebook every time I pair the phone to the unit so you can call by selecting a contact.

Someone can help me?. Today I have rooted my unit and the problem with the phonebook is going on as before the unit root.

I wonder if someone else happens this. I also thought it my phone problem.

1 din pure Android car head unit

Hi kaween, thanks for the info and your are right. I have not been able to see any threads on rooting a WinCE + Android unit. I would probably buy a pure Android head unit and try to root it. Unfortunately, there is no space in my car that can fit a 2-Din HU and 1-Din pure Android HU is hard to find. I checked with Hifimax and they informed me that they have stopped selling 1-din units. Pumpkin does not seem to have 1-din pure Android unit either. Do you know where I may be able to buy one?

How do you get the key to stay illuminated on S150 ? They turn on (blue on mine) for a moment but turn off after that. Maybe I did not read the manual, but you mentioned they turn red on your unit.

---------- Post added at 09:11 PM ---------- Previous post was at 09:09 PM ----------

Try eBay. Other site from where I buy stuff directly from China is Aliexpress. There are a few others, use google, you may find a unit.For example searching on Aliexpress for "1 din android" gives you a list with the first one :http://www.aliexpress.com/item/1-di...r-Radio-7-inch-Detachable-WIFI/870384811.html

Also, if your car is not very old, you may find a custom fitted unit with a front plate and a required harness cables. Some car units will replace a big junk of your dash so it may integrate a 2 DIN unit inside. Search for your car type and year and see what's available.Your choice. Don't expect to much support when you buy a unit like this (without kaween my unit would not have the steering wheel controls working). You may have more luck, depending of the seller you buy from For rooting you are pretty much on your own but there are some utilities which work with many units. For the S150 this one works: http://xdaforums.com/showthread.php?t=2110546&page=111.

If the unit has OTG working (so you can connect to it via a PC like on any tablet and phone, you have even more options for rooting.I rooted my Chinese MTK based phones without problems with this one: http://xdaforums.com/showthread.php?t=1886460, but again you need the "device" mode working on your unit and be able to enable debug mode. You will not know until you try. Good if you find a unit which is better known like those in this thread.
